      vmbr0=10.0.0.>eno1>network switch (and gateway is set to pfSense gateway) using nano /etc/network/interfaces

      ISP>enp1s0f0 (WAN)
      LAN=enp1s0f1>network switch

      I don't understand "network switch" on vmbro...hope you don't have a switch there...any network switch must attach to pfSense LAN.

      The pfSense WAN and LAN must be passedthrough. If you have a switch, put it on pfSense LAN, you can connect an Ethernet cable from proxmox's management port to it to have access to both pfSense LAN and Proxmox. Remember DNS also. In the screenshot below, you will be able access Proxmox and pfSense webGUI with the same browser with different tabs...in mine, I have Proxmox, pfSense, and FreePBX.

        @NollipfSense okay well there might have been some slight miscommunication on my end. vmbr0 is bridged to eno1 (which is what eno1 is set to on proxmox the default bridge set up) which is going to the network switch. is that wrong?!?!

        I have the total of 3 bridges
        vmbr0 =10.0.0.xx and to pfsense gateway is set to the gateway,
        vmbr1 = WAN on pfsense
        vmb2 i= LAN on pfsense

        the DNS is from my isp as well as google, but i plan to make my own DNS server so that i am more private.

        pfSesnse DNS:
        8.8.8.8,
        8.8.4.4 (google)

        Proxmox DNS

          Well, if your gateway for Proxmox is pfSense LAN, then it would make sense to put the switch on pfSense LAN and connect Proxmox's management port to the switch ensuring Proxmox know its gateway.

          Proxmox DNS, as stated before, should be pfSense and set this as well as this, see below:

          Not needed since Proxmox management will be apart of pfSense LAN...see below, I have none, other than default. Note, you will need one, if and only if, you have port forward or VPN later.

            okay so i went to nano /etc/resolv.conf
            changed the DNS to
            127.0.0.1
            8.8.8.8
            8.8.4.4

            added the LAN Rule
            and i still get nothing

              @Papa_Dragon It seems as if you're not following instructions given. Also, you need to read up on pfSense as much as possible. A statefull firewall, such as pfSense, nothing can enter the WAN unless the request comes from LAN; so, putting these rules on WAN is pointless...they're not doing anything...see the circle on the pic below. You were told to leave WAN with the default rule it had OR read Netgate document on WAN.

              Screenshot 2023-06-07 at 2.53.57 PM.png

              What's this 10.0...that's not a complete IP address...please disclose the full address. If you look at the circle, LAN.net tried to contact this 10.0 address BUT the address is not responding. Now, look at your DNS below the circle...you see that your DNS is working...

                i understand the confusion. And i apologize if I am making this difficult. in my defense i had no idea what pfsense was... until like 2 months ago. this is a new hobby for me, with a huge learning curve and i am excited to enter the world but didn't realize how much work it would be, but i can assure you that i am willing to learn. i am trying my best to follow your instructions, but i mostly go off of your pictures to understand what to do. i wouldn't be on this forum if i knew what i was doing, but sense its new to me I am reaching out and asking for help because i have a very small percentage on what i am doing. So again i am sorry if this is frustrating.

                for the wan i have portforward that i would not like to disclose, as it may or may not be exposed to the world and a potential security risk. all i well say is that its a game server that i have set up with my buddies. it appears that its doing nothing but infact it is. Also for the LAN it was a complete address. i just photo shopped it to block out any potential security risks.

                  Learn to use firewall alias...they're awesome firewall tools so you can show without disclosure. Also, ping LAN.net from 10.0.0.15...make sure the protocol is IPv4 TCP/UDP so we know that also works

                    so i tired to ping on my server i only have access to it due to a mouse and keyboard, and a monitor, but i cant ssh in. i tired ping LAN.net (from my server aka 10.0.0.15) and i got this as a result. temporary failure in name resolution

                    which one should be the TCP/UDP?

                      Select both...port 8006 is UDP and update Proxmox will use TCP.

                        is this what you meant? also sorry for the late reply ( i guess early lol for me at least). would adding another LAN for my eno1 work? like if i went back and accessed my proxmox and added the vmbr0(aka eno1)? would disabling the proxmox firewall work? I'm just trying to figure it out

                        also this is Photoshopped!! dont worry its not blank...!Screenshot (23).png

                        edit when i was assigning, the gateway i used the WAN gateway. but I've noticed that any time i connect a device to my LAN it gets a different gateway. so should i have put the LAN gateway or the WAN gateway??

                          Only your LAN has a gateway...WAN just connects you to the Internet...your network is LAN.

                          That's because you still have it the same way in your original post despite several instruction. Maybe, that's why you have this, see below. Since you have port forwarded, that suggest you have some server function other than Proxmox. So, that seems to suggest you're implementing a sophisticated network. That's fine however, you must know what you're doing. A network diagram would be best for us to see what you want to accomplish.

                              You image is invalid file type for the forum. This primitive image is how I imagined your network...see below. In your ISP router mode, you have access to Proxmox while ISP router in bridge mode, you don't have access. The drawing should help you see why.

                              Screenshot 2023-06-08 at 4.04.36 PM.png

                              This image below is what you were told to do and since your Dell has a four-port NIC, you have two for pfSense WAN and LAN, one for Proxmox, and the other you can use for your port forward. Does this helps?

                                  @Papa_Dragon okay to clarify

                                  1. swap promox to pfsense LAN gateway?

                                  2. swap dns using nano /etc/resolv.conf (done)

                                  3. change IPv4 tcp protocol to TCP/UDP?

                                  i tried for the caveman drawing, sorry if its bad

                                  this is the written version of what i have set up

                                  1. internet>modem (in bridge mode) then from there 2 port NIC card (pfsense WAN and LAN interfaces) enp6s0f0 is made into WAN LAN is enp6s0f1 same NIC. there are 3 bridges in total and they go as follows:

                                  vmbr0=eno1 (OG 4 port NIC)

                                  vmbr1= enp6s0f0 (pcie NIC)

                                  vmbr2= enp6s0f1 (pcie NIC

                                  1. then on that same NIC, i have the LAN going off to my network switch. done.

                                  2. the OG port for Proxmox is eno1 (not a "0" btw) that is hooked up to the network switch. done

                                  so total 2 ethernet cords that are currently in my switch.

                                  how i started/set up my VM on Proxmox

                                  shaw modem is not in bridge mode

                                  -named it pfSense

                                  -chosen my hardware, ram, cpu cores, then on the networking page i said no, to default vmbr0 and opted to choose my own

                                  • hit finish

                                  • went over to hardware tab on VM and input vmbr1 (WAN) vmbr2(LAN) i even labeled them to not get things messed up

                                  -made sure to hit boot at start

                                  -booted it up

                                  -then when it asked me for Vlan i said no

                                  -then opted for me to choose an interface. WAN is as stated earlier same for LAN

                                  • hit 2 on the pf boot menu

                                  -set my own LAN ip address for pfSense

                                  -proceeded to add a range for pfSense for my LAN

                                  now what is on the switch (if its important) is as follows

                                  • I have the pfsense LAN

                                  • Proxmox eno1

                                  • a wifi router to get wifi in my house

                                  • smart lights

                                  • PS5

                                  what i have set up on my pfsense firewall

                                  WAN

                                  nothing

                                  LAN

                                  -i have a portforward for a game server for my friends and I

                                  • i also have those "proxmox management"

                                  • DNS

                                  and other things in that photo

                                  this is everything, i hope this clarifys things a little.

                                  i apolozige that you need to repeat yourself its just a little over my head and the way i learn or at least know what to do is by a list of things like what i typed. so for example if i created a new LAN rule, it helps me understand if i know what to put. so it goes like this

                                  interface: LAN

                                  protocol: any

                                  source : blah blah

                                  and so on and so forth

                                      @Papa_Dragon i got it up and running!!!!

                                      So heres what I got done. I double-checked everything to make sure it was all up and running.

                                      for anyone reading this issue

                                      Here's a step-by-step walkthrough of the process, divided into sections:

                                      Proxmox Setup:

                                      Set up Linux bridges:

                                      Create two Linux bridges: vmbr1 and vmbr2.
                                      Assign enp6s0f0 to vmbr1 and enp6s0f1 to vmbr2.
                                      Set up the VM:

                                      Install the desired operating system in the VM.
                                      During the VM creation process, choose "No network device" as the network configuration.
                                      Configure VM settings:
                                      Go to the VM's options and enable the "Start at boot" option.

                                      pfSense Setup:

                                      Set up WAN and LAN interfaces:

                                      Configure the WAN interface of pfSense to connect to the modem in bridge mode.
                                      Assign enp6s0f0 as the WAN interface.
                                      Assign enp6s0f1 as the LAN interface.

                                      Configure firewall rules:

                                      Create appropriate firewall rules to allow desired traffic between WAN and LAN.

                                      Network Setup:

                                      Assign IP addresses:

                                      Set the LAN IP range for pfSense
                                      Set the gateway for vmbr0 (OG 4 port NIC) to LAN gateway make sure its the LAN

                                      Set static IP for Proxmox:

                                      Configure the Proxmox server with the static IP address 10.0.0.15 (or any available IP within the IP range you set).
                                      Use a subnet mask of 255.255.255.0
                                      and set the default gateway to the LAN.

                                      Connect your computer to the LAN side of pfSense (aka Switch):

                                      Pluged my computer into one of the ports on the network switch connected to the LAN side of pfSense.

                                      Configure your computer's IP address:

                                      this is where i had issues!!!!!!!!

                                      i had to Set your computer's IP address to be within the same network range as the Proxmox server.
                                      Assign an IP address of 10.0.0.xx
                                      Use a subnet mask of 255.255.255.0
                                      gateway: LAN of pfSense

                                        i had to Set your computer's IP address to be within the same network range as the Proxmox server.

                                        I told you repeatedly, even drew an ugly looking diagram because I didn't want to spend valuable time with a network fancy diagram...wow! Glad you finally got it.
